TL;DR

A second-tier regional bank based in Okinawa Prefecture (TSE STD 8554, abbreviated “Kaigin” / “Kaigin”). Established as 1949 Kokuba Mutual Bank (under U.S. military government, in the B-yen-currency era before reversion to Japan) → converted to a Japanese bank license at 1972-05 Okinawa’s reversion to Japan → 1989-04 conversion to an ordinary bank (joining the Second Association of Regional Banks). As the No.3 financial institution within Okinawa Prefecture, against the two-strong structure of the top 2 行 (within-prefecture No.1 = Bank of Okinawa, under okinawa-fg; No.2 = Bank of the Ryukyus, ryukyu-bank), it has secured a third-force position through a community-based niche strategy of SME lending + personal lending + tourism + U.S. military base economy + covering the remote islands. Its deposit-lending share is around the 10% level within the prefecture. Its head office is in Kumoji, Naha City (the same area as Bank of Okinawa and Bank of the Ryukyus, within walking distance).

1. Company overview

Legal name: The Okinawa Kaiho Bank, Ltd. English name: The Okinawa Kaiho Bank, Limited Securities code: TSE STD 8554 (TSE Standard market) Established: 1949 (established as Kokuba Mutual Bank, in Okinawa under U.S. military government) Conversion to an ordinary bank: 1989-04 Head office: Kumoji, Naha City, Okinawa Prefecture Form: Standalone listed bank (no holding company) Membership: Second Association of Regional Banks (the group converted from former mutual banks / mujin)

History from establishment to conversion to an ordinary bank

1949 Kokuba Mutual Bank established (capital denominated in B-yen, under U.S. military government)
- Founding base: Okinawa Prefecture’s business circles, responding to the SME and ordinary-citizen finance needs of the postwar Okinawa economic-recovery period
- The trade name “Kokuba” derives from a place-based naming after the Okinawa-Prefecture conglomerate Kokuba-gumi (the lineage of Kotaro Kokuba, who was also involved at the founding of okinawa-fg Bank of Okinawa) ^[likely]
1972-05-15 Okinawa’s reversion to Japan
- B-yen / U.S.-dollar-denominated operations under U.S. military government → shifted to yen-denominated operations
- Transferred to a licensed bank under Japan’s Banking Act / Mutual Bank Act
**Around 1976 ** becoming “Okinawa Mutual Bank” through a trade-name change (the timing requires confirmation) ^[likely]
1989-04 in connection with the mutual bank → ordinary bank en masse conversion (abolition of the Mutual Bank Act, establishment of the Second Association of Regional Banks), changed its trade name to Okinawa Kaiho Bank and converted to an ordinary bank
TSE listing (TSE 2 section, later the Standard market, current code 8554) ^[likely]

Position within Okinawa Prefecture’s 3 行 oligopoly structure

Bank	Within-prefecture position	Deposit-lending share	Established	Form	Listing
Bank of Okinawa (under okinawa-fg)	Within-prefecture No.1	approx. 30%	1956	Trust-combined + holding-company formation (2021-10)	PRIME 7350 (FG)
ryukyu-bank (Bank of the Ryukyus)	Within-prefecture No.2	approx. 25% level	1948 (USCAR ordinance)	Standalone listed bank	PRIME 8399
Okinawa Kaiho Bank (Kaigin)	Within-prefecture No.3	approx. 10% level	1949 (Kokuba Mutual Bank)	Second-tier regional bank, standalone listing	STD 8554

Within-prefecture No.1 and No.2 form the “Bank of Okinawa / Bank of the Ryukyus two-strong” structure → Kaiho Bank has a structure in which its scale gap as a second-tier regional bank remains directly as a competitiveness gap
On the other hand, it maintains its community network in niche areas that the two strong banks cannot fully cover, such as SMEs / individuals / remote islands / around the bases

Major subsidiaries / affiliates (overview of public information)

Okinawa Kaiho Bank (standalone listing 8554)
  ├── Kaigin Guarantee ── credit guarantee (the company name is based on the common name in the public portion) ^[likely]
  ├── Kaigin Business Service ── back-office agency ^[likely]
  ├── Kaigin Economic Research Institute / think-tank function (small scale, smaller than Bank of Okinawa's "Okigin Economic Research Institute" and Bank of the Ryukyus' "Ryugin Research Institute") ^[likely]
  └── Card / leasing tie-ups ── JCB / DC affiliated cards, affiliated leasing (in-house + tie-up structure) ^[likely]

Subsidiary scale and names should be checked against the latest disclosure publication. Because it is No.3 in scale within Okinawa Prefecture, it has a structure centered on core banking operations rather than the systematic group expansion of Bank of Okinawa and Bank of the Ryukyus.

2. Business segment map

Segment	Characteristics
SME lending	Lending to within-prefecture SMEs and small-scale businesses is the mainstay. Close relationship-based sales to the micro-business tier that Bank of Okinawa and Bank of the Ryukyus cannot fully cover
Personal lending / mortgages	Personal loans such as within-prefecture mortgages, card loans, and education loans
Tourism-industry lending	For resorts / hotels / tourism-related businesses (competing with Bank of Okinawa and Bank of the Ryukyus)
U.S. military base economy	Deposit accounts for businesses around the bases / base-related construction contractors / U.S. service members and civilian personnel
Covering the remote islands	Maintaining within-prefecture remote-island branches such as Miyako, Yaeyama, and Kumejima. A branch network as regional infrastructure
Public funds / local public bodies	The designated financial institution for Okinawa Prefecture is fixed by alternating-year mandates between Bank of Okinawa and Bank of the Ryukyus; Kaiho Bank’s are mainly designated-fund relationships at the municipal level ^[likely]
Cards / settlement	JCB / DC affiliated cards, participation in regional QR settlement
Syndicate participation	A second-tier role participating in syndicates lead-managed by Bank of Okinawa and Bank of the Ryukyus on large within-prefecture deals

Strategic themes specific to second-tier regional banks

As common issues for member banks of the Second Association of Regional Banks (former mutual banks):

The wall of scale: the capital-scale and credit-rating gap with first-tier regional banks (Bank of Okinawa / Bank of the Ryukyus). Lead-managing large deals is difficult
SME / micro-business specialization: differentiating not in areas where it cannot win on scale, but through close relationship-based sales / small-lot lending / speedy screening
Digital-investment burden: standalone systems investment for a second-tier regional bank is a heavy burden → using shared centers / participating in a regional-bank cooperative body

Linkage with Okinawa’s economic characteristics

V-shaped recovery in tourism: recovery in inbound tourist numbers, full operation of Naha Airport’s 2 runway, JUNGLIA (a northern theme park opening at 2025-07 ), and other large within-prefecture tourism projects → Kaiho Bank also benefits from lending to tourism-related businesses
U.S. military base economy: lending to businesses around the bases / handling of dollar-denominated products
Remote-island finance: everyday finance for SMEs and residents on the remote islands
Okinawa promotion budget: functions as a within-prefecture channel for the promotion-lending system based on the Okinawa Promotion Special Measures Act (extended 2022-04 10 )

Competition / cooperation relationships

Within-prefecture 3 行: an oligopoly among Bank of Okinawa (okinawa-fg), ryukyu-bank, and Kaiho Bank. Together with 3 行, the head offices are concentrated in close proximity around Kumoji, Naha City (a within-prefecture financial-district structure)
okinawa-shinko (Okinawa Development Finance Corporation): a policy-finance complementary relationship. The standard pattern is for within-prefecture businesses to raise funds with the ODFC, which holds a Shoko Chukin-like position, + private-sector 3 行
Megabanks: differentiated positioning with the within-prefecture bases of mufg / smfg / mizuho-fg on large corporate deals
Second Association of Regional Banks membership: information sharing and mutual-ATM tie-ups with the nationwide second-tier-regional-bank network (fidea-hd / jimoto-hd, etc.)

Reorganization scenario

The status quo maintains equilibrium. Unlike the integration cases of mainland second-tier regional banks (fidea-hd / Kita-Nippon FG, etc.), in Okinawa the 3 行 oligopoly has been stable over the long term

4. Regulation / policy

Supervisor: FSA
Regional supervision: Okinawa Finance Office of the Fukuoka Local Finance Branch Bureau
Member association: Second Association of Regional Banks (the body of the group converted from former mutual banks / mujin)
Okinawa-specific regulation:
- Financial-preference systems tied to the Okinawa Promotion Special Measures Act
- Cooperation with the Okinawa Prefecture Credit Guarantee Association
- Coordinated lending with the Okinawa Prefecture Promotion Corporation (okinawa-shinko)
Recent policy points:
- 2024〜 BOJ policy-rate normalization → recovery in deposit-lending margins (a tailwind for second-tier regional banks as a whole)
- Expanding lending demand accompanying the V-shaped recovery in tourism
- The judgment between remote-island branch-maintenance costs vs. digitalization as a substitute
- Medium-to-long-term trends in the Okinawa promotion budget (review of promotion measures after the 50 anniversary of reversion to Japan)

okinawa-fg — Within-prefecture No.1 (Bank of Okinawa’s parent company, 2021-10 holding-company formation)
ryukyu-bank — Within-prefecture No.2 (1948 established by USCAR ordinance, standalone listing)
okinawa-shinko — Okinawa Development Finance Corporation (policy-finance complement)
fidea-hd · jimoto-hd — Integration cases of mainland second-tier regional banks (reorganization comparison targets)
mufg · smfg · mizuho-fg — Mega 3 行 (competition / correspondent on large within-prefecture deals)
